Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QSE-020-01-L-D-K is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration (Receptacle, Center Strip Contacts)
• Electrical specifications (40 positions, 0.031" pitch, 2 rows)
• Physical dimensions (Height above board: 0.128", mated stacking heights)
• Surface mount mounting type
• Contact material and finish (Gold, 10.0µin thickness)
• Compliance certifications (RoHS3, MSL 1)
• Series designation (Q Strip® QSE)

The primary variable among equivalent parts is packaging format. The QSE-020-01-L-D-K is supplied in Tray packaging, while substitute parts may be available in alternative packaging configurations such as Tape & Reel (TR) format. This distinction affects inventory management and automated assembly processes but does not alter the electrical or mechanical performance of the connector itself.

Parameter Comparison

Engineering Selection Recommendations

Both the QSE-020-01-L-D-K and QSE-020-01-L-D-K-TR are Active products from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on manufacturing and supply chain requirements:

The Tray-packaged QSE-020-01-L-D-K is suitable for manual assembly operations, kit builds, and lower-volume production runs where individual component handling is standard practice.

The Tape & Reel packaged QSE-020-01-L-D-K-TR is optimized for automated pick-and-place assembly processes and high-volume manufacturing environments. This format integrates directly with standard surface mount assembly equipment.

Both variants maintain full RoHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes and storage conditions. No additional environmental or handling considerations apply when substituting between these packaging formats.

Frequently Asked Questions (FAQ)

Q: Can QSE-020-01-L-D-K-TR be used as a direct substitute for QSE-020-01-L-D-K?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus Tray). The connector itself performs identically in the application.

Q: Does packaging format affect connector performance or reliability?

A: No. Packaging format is a supply and assembly logistics consideration only. It does not alter electrical performance, mechanical fit, contact resistance, or long-term reliability of the connector.

Q: Which packaging format should be selected for automated assembly?

A: Tape & Reel (TR) format is designed for automated pick-and-place equipment. The QSE-020-01-L-D-K-TR integrates directly with standard surface mount assembly lines.

Q: Are there any compliance or certification differences between the two packaging formats?

A: No. Both variants carry identical RoHS3 compliance and MSL 1 ratings. Certification and regulatory status are unchanged by packaging format.

Q: What are the mated stacking height options for this connector?

A: The QSE-020-01-L-D-K supports mated stacking heights of 5mm, 8mm, 11mm, 14mm, 16mm, 19mm, and 25mm, allowing flexibility in connector stack configurations.

Q: Is moisture sensitivity a concern for storage or handling?

A: No. Both parts carry MSL 1 rating, indicating unlimited shelf life without moisture sensitivity constraints. Standard storage conditions apply.
